Earning points on "Eligible transactions"

[frequentflyer]

How strict are credit card providers on their definition of "Eligible transactions"?

I'm thinking about putting a ~$6k corporate expense (purchasing a report) onto my rewards card as I am currently getting 3x points under an introductory offer. The T&C's exclude transactions made in operating a business but I am not sure how strict they are or if they check at all. I have another card that will earn me 1 point from this transaction but am really hoping to get the triple!

My card provider is Virgin Money, which is operated by Citi.

I put a $10k work function on one of my bank Amex cards and didnt have any issues getting the points.

I put around $60K a month on my High Flyer without a problem so far.
